I dont QT either...dont have the means to. Which scared me the other day when my blue hippo had a white spot on his nose...did a big water change the next day ha. Strange that they "host" the xenia during the day and the anemone at night. When they get bigger they will most likely kill everything else in the tank, so be ready to have maroon only display. My brother had one in a 125 that he had to get rid of because it was beating up a sailfin and killing everything else. Mean little bastard.
